TOP DIVE DESTINATIONS IN MEXICO

Episode 2: Cabo Pulmo – The Aquarium of the World

 

Hidden along the eastern coast of Mexico's Baja California Peninsula lies one of the greatest marine conservation success stories on Earth.

Cabo Pulmo National Park is home to the oldest coral reef on the west coast of North America and one of the most remarkable examples of how marine protection can restore an entire ecosystem.

Once threatened by overfishing, Cabo Pulmo has transformed into a thriving underwater paradise where enormous schools of fish, healthy coral reefs, sharks, sea lions, and massive pelagic species flourish.

It is no surprise that Jacques Cousteau famously referred to the Sea of Cortez as "The Aquarium of the World."

Why Dive Cabo Pulmo?

Established as a National Marine Park in 1995, Cabo Pulmo became a fully protected no-take marine reserve.

Since then, fish biomass has increased by more than 460%, making it one of the most successful marine conservation projects ever documented.

Today, divers experience an underwater world that closely resembles what much of the Sea of Cortez looked like decades ago.

Every dive is filled with life.
